Acute toxicity studies of propiverine hydrochloride (P-4) were carried out in mice, rats and dogs of both sexes. 1. The LD50 values of P-4 were as follows: Mice; 410 (male) and 323 (female) mg/kg in oral route, 223 (male) and 283 (female) mg/kg in subcutaneous route and 36 (male and female) mg/kg in intravenous route, Rats; 1000 (male) and 1092 (female) mg/kg in oral route, 1632 (male) and 1411 (female) mg/kg in subcutaneous route, and 22 (male) and 25 (female) mg/kg in intravenous route. On the LD50 values, no sexual difference was apparent but the species difference between mice and rats observed to be present in oral and subcutaneous routes. The approximate lethal doses of P-4 in dogs were 987-1137 mg/kg for male and 865-894 mg/kg for female in oral route, and the values were almost same as those in rats of oral route. 2. Major toxic signs such as clonic convulsion, bradypnoea, dyspnoea, decreased spontaneous activity and hematuria were observed in mice and rats. Furthermore mydriasis in rats, and transitory salivation and/or vocalization in mice and rats were observed. In some rats, sedation, salivation, soil at hypogastrium, rale and emaciation were detected from the next day of oral administration. In dogs, toxic signs such as vomiting, tremor, tonic and/or clonic convulsion, mydriasis and gasping were observed. 3. Pathological changes observed in dead animals were congestion of lungs, liver and kidneys in all routes, congestion and hemorrhage in digestive tracts in oral route, inflammatory changes at the injection site in subcutaneous route. In addition, retention of hematuria in urinary bladder in rats of oral and subcutaneous routes, the hemorrhagic changes of heart, atonia of urinary bladder and retention of urine in dogs were observed. 4. The main cause of death seemed to be respiratory disturbance in all species and the weakness in a few rats of oral route.

A 67-year-old woman was admitted to our hospital with chest pain and dyspnea which occurred suddenly after vomiting. She was well until admission except for cholelithiasis and hypertension which had been pointed out 3 years earlier. Arterial blood gas analysis showed hypoxemia without hypercapnea. Chest X-ray examination on admission revealed intra-mediastinal air with a niveau behind the heart which compressed the vasculature of the left lower lobe and a small amount of air in the regions adjacent to the trachea, left main bronchus and aortic arch. The serial chest radiographs showed pneumomediastinum, subcutaneous emphysema, pneumothorax and pleural effusion in that order within 16 hours after the onset. The diagnosis of esophageal rupture was made by CT scan of the chest performed after oral administration of Gastrografin, which demonstrated extravasation of contrast medium into the mediastinum. Surgical treatment including eversion stripping and esophagogastrostomy was performed 23 hours after the onset. Pathological examination of the removed specimens revealed a rupture of the lower portion of the esophagus originated in the gastric ulcer of the cardia. In spite of intensive care, she died 45 days after surgery because of renal failure. It was considered that the most important point in the early diagnosis of esophageal rupture was to suspect this disease based on the gastric symptoms followed by the respiratory symptoms and to demonstrate pneumomediastinum in chest X-ray. Chest CT scan performed after the oral administration of contrast medium could be an useful and non-invasive diagnostic procedure.

Leiomyoma of the esophagus is not uncommon in the adult population but is rarely seen in children; only 20 cases have been reported in the pediatric population. In this paper we describe two cases of esophageal leiomyoma in female patients aged 6 and 13 years and review previous reports. Several differences were noted between the pediatric and adult population. The mean age in children is 14 years (range, 4 to 20 years). Leiomyoma appears 1.71 times more often in females than in males. Localized lesions are found in only 9%, whereas the diffuse form predominates in 91%. The entire esophagus may be involved 35% of the time, and encroachment on the cardia or upper stomach occurs in 70%. Leiomyomas associated with familial syndromes (familial leiomyoma and Alport's syndrome) occur in 22% of the cases. Major symptoms include dysphagia (86%), dyspnea (36%), vomiting (27%), retrosternal pain (27%), and coughing (22%). The initial diagnosis following contrast studies is most often achalasia. The diagnosis of leiomyoma is made only with subsequent endoscopy. Enucleation was performed in only 11% of the cases; surgical resection (including part of the stomach) was necessary in 78% with a 21% postoperative mortality. Esophageal leiomyoma should be considered in the differential diagnosis of mediastinal masses and esophageal obstruction. Accurate preoperative diagnosis is desirable in order to plan proper surgical treatment.

A prospective, randomized comparative trial was carried out in 31 children suffering from lower respiratory tract infections, mainly bronchopneumonia or pneumonia. Twenty-one children received oral cefetamet pivoxil in a dose of 20 mg/kg/day (10 children) or 40 mg/kg/day (11 children), and 10 children 30 mg cefaclor/kg/day for 7 days. Clinical signs and symptoms, i.e. fever, dyspnoea, altered breath sounds and cough, subsided during treatment with both cefetamet pivoxil treatment doses in all patients. All X-ray findings and blood leucocytosis normalized, while 1 out of the 10 children to whom 30 mg cefaclor/kg/day was administered deteriorated from bronchopneumonia to pneumonitis during treatment. Treatment was stopped due to vomiting in 1 patient receiving the 40 mg cefetamet pivoxil/kg/day dose.

Methyl tertiary butyl ether (MTBE) rapidly dissolves cholesterol gall stones in vitro and in vivo. To further characterise tolerability and safety of this aliphatic ether, either MTBE (1 ml/kg body wt daily for two days) or an equal amount of saline was infused into the common bile duct (CBD) of eight cholecystectomised rabbits. Transient vomiting, dyspnoea and somnolence developed during MTBE instillation. Post-treatment values of serum transaminases and alkaline phosphatase were significantly higher in MTBE than in saline treated animals. Cholangiography one week after the last intraductal infusion showed a five-fold increase of CBD size in MTBE v control rabbits. At autopsy histological signs of chemical cholangitis and mild duodenitis were noted in MTBE treated animals. Prompted by these findings, we performed a cholangiography in two patients who had received intraductal MTBE (about 0.2 ml/kg body wt daily for one or two days) one year before: an abnormal dilatation of the CBD was present, which might represent a specific, hitherto undescribed permanent sequela of MTBE administration.

Spontaneous rupture of the diaphragm during normal labour is extremely rare. It requires emergency surgical correction. The authors report what they believe is only the second reported case. Eleven hours after delivery of a male infant, a 27-year-old woman experienced severe epigastric pain, vomiting and dyspnea, followed by cardiopulmonary arrest. Although the ruptured diaphragm was diagnosed and repaired, she suffered severe anoxic encephalopathy and died 3 weeks after operation without regaining consciousness. Clinicians must be aware of the existence of this rare condition because failure to diagnose and treat the ruptured diaphragm will almost certainly lead to the patient's death.

Interleukin-2 (IL-2) and beta-interferon (beta-IFN) are cytokines with profound immunobiological effects on T-cell and natural killer (NK) cell activity; IL-2 also induces lymphokine-activated killer (LAK) cell cytotoxicity in humans. Both lymphokines induce antineoplastic activity against several refractory tumors. This Phase I study of 50 patients assessed the toxicities, maximally tolerated dose (MTD), effects on certain immune effector cells, pharmacokinetics of IL-2, and development of antibodies to the combination of subcutaneously administered IL-2 and intravenously administered beta-IFN. Fever was common. Indomethacin reduced the incidence and severity of fever and was necessary to prevent it from becoming dose-limiting. Hypotension occurred but never required pressors or produced complications. Constitutional symptoms, local skin toxicity at the site of IL-2 injection, generalized desquamation, eosinophilia, nausea, and vomiting were also observed. One patient had reversible renal dysfunction. Two patients experienced drug-related dyspnea without evidence of capillary leak syndrome; neither required intubation. Fluid retention and cardiotoxicity were not observed. The MTD was 5 x 10(6) U/m2 s.c. of IL-2 and 2 x 10(6) U/m2 i.v. of beta-IFN when given in combination. Enhancement of in vivo NK cell cytotoxicity and proliferation of T4+, T8+, and NK cells occurred. In vivo induction of LAK cell cytotoxicity was observed in three patients. Four patients developed nonneutralizing anti-IL-2 IgG antibodies, but none developed antibodies to beta-IFN. Peak IL-2 serum levels typically occurred 4 h following drug administration. Serum levels were within a factor of 3 of the peak level in the period studied, 1-6 h postinjection. No complete responses occurred. One patient with rectal cancer and one with transitional cell carcinoma each had a partial response, and 13 other patients (5 with renal cell, 4 with colorectal, and 4 other cancers) had stable disease. Induction of NK cell cytotoxicity was seen more commonly in patients with stable disease than in those with progressive disease. Combined administration of these agents is feasible with acceptable toxicity, and Phase II trials are warranted.

A twenty-seven-year-old 25 weeks gestation female was admitted with recurrent symptoms of nausea, vomiting and epigastric pain. She was diagnosed as left diaphragmatic hernia by chest X-ray film, CT and esophago-gastrography. During operation, a left central tendon defect was observed, and was 3.5 cm in diameter. The margin of the defect was smooth and round. It was associated with diaphragmatic eventration. The small intestine and transverse colon were herniated into the left thoracic cavity. The central tendon defect was closed with direct mattress sutures and was reinforced by overlap-technique of the diaphragm. To our knowledge, this type of defect has not been described previously in Japan. Diaphragmatic hernia in pregnancy is very rare, and presents abdominal pain, vomiting and dyspnea. Usually the diagnosis is achieved by chest X-ray film. However, esophago-gastrography should be added, if the diagnosis could not be confirmed by chest X-ray film. Conservative management is reported to bring high mortality, therefore, prompt surgical repair is advisable.

Clinical signs of esophageal hiatal hernia in four dogs and one cat included regurgitation, vomiting, hematemesis, hypersalivation, dysphagia, and dyspnea. Thoracic radiographs, esophagram, and fluoroscopy were used to demonstrate cranial displacement of the esophagogastric junction and part of the stomach through the esophageal hiatus. Other findings included megaesophagus, esophageal hypomotility, gastroesophageal reflux, and pneumonia. Medical therapy failed to resolve the clinical signs. Reduction in size of the esophageal hiatus, fixation of the esophagus to the diaphragmatic crus (esophagopexy), and a left fundic gastropexy were performed. Surgical results were considered good to excellent.

The effects of eight neuroleptic drugs injected into the cerebral ventricles on behavior, autonomic and motor activity of unanesthetized cats have been studied. Chlorpromazine, trifluorpromazine, droperidol, haloperidol, domperidone and spiperone induced emotional behavior (restlessness, miaowing, rage, attack, defense, fighting with paws, biting), autonomic (mydriasis, tachypnoea, dyspnoea, panting, salivation, defecation, urination, licking, vomiting) and motor (ataxia, muscular weakness, adynamia) phenomena. The main and the most consistent effect was the motor impairment, while the aggression was inconsistent and of moderate intensity. Of the neuroleptic drugs injected, only spiperone, domperidone and trifluorpromazine produced a dose-dependent motor impairment. The autonomic effects were also inconsistent and of low intensity. Metoclopramide induced inconsistent autonomic and motor effects, while sulpiride was devoid of any visible behavioral, autonomic and motor activity. It appears, therefore, that the motor impairment as well as the aggression caused by the neuroleptic drugs is perhaps related to central D-1 rather than to central D-2 dopamine receptors, but an effect on central norepinephrine and on central serotonin receptors cannot be excluded.
